So with that Mt Xinu Mach/386 thing I thought I’d take another stab at building the source from the CSRG CD-ROM set.

The makefiles from the i386 version are so cut up it’s a seemingly hopeless mess.  I took the mach.kernel.mk directory and tried to build of 4.3BSD UWisc, but that went nowhere quick as the tool chain just isn’t right and there is a bunch of VAX stuff missing.  It looks more complete for the SUN-3.

So in a fit of rage, I copied the bare needed i386 files into the SUN-3 tree and it actually compiles.

ROUGH notes….

Mach25 is where I put the 386 directory & running from inside the mach.kernel.mk directory.

mv ../mach25/sys/i386 .

mv ../mach25/sys/i386at .

mv ../mach25/sys/mach/i386 mach

mv ../mach25/sys/sysV .

cp ../mach25/sys/conf/*i386* conf

ln -s i386 machine

ln -s mach/i386 mach/machine

cp Makeconf Makeconf-orig

vi Makeconf

Naturally the Mt Xinu bootloader won’t run it.

That’s all I get out of it.  I’ll have to mess with it later on as it’s getting late, but I thought it was worth sharing.
